Starting with Census 2010, the decennial census and annual American Community Survey (ACS) are integrally connected. This section is focused on topics concerning Census 2010/ACS data access and use, applications using these data and the integration and analysis of these data with other data.
Census 2010 has its own focus page.
The American Community Survey (ACS) is a nationwide survey designed to provide more frequently updated demographics
for national and sub-national geography than provided by the decennial census program.
The ACS collects and produces population and housing information every year instead of every ten years.
ACS is integrally connected with Census 2010.
This section is focused on topics concerning ACS data access and use, applications using these data and the
integration and analysis of these data with other data.

10.11.10 America's Urban Areas ... comparing Census 2000 & ACS 2009
The urban population of the United States increased from 222.3 million in 2000 to 234.8 in 2009,
an increase of 12.5 million or by 5.6 percent. The percent urban population decreased from 79.0 percent in 2000
to 76.5 percent in 2009. The 2000 data are as of April 1, 2000 and based on
Census 2000 and are "complete count" data.
The 2009 data are 2009 American Community Survey (ACS) 1 year estimates.

09.10.10 ACS 2005-09 Block Group Subject Matter Tables
New American Community Survey(ACS) 2005-09 national scope
estimates will become available in December.
While this is a ACS topic, and not technically a Census 2010 topic,
these new small area demographics will be of interest to most Census 2010 data users.
See more in general about the block group estimates in the 9.9.10 item on this page.
Unlike other geographic tabulation areas, ACS 2005-09 block group (BG) estimates are developed only in the form of "detailed tables"
and are only published in the form of downloadable summary files. ACS BG level data are not accessible interactively online via FactFinder.
There are no demographic profiles available for block groups from the Census Bureau, although these are developed by Proximity.
An interactive table
provides a list of the detailed tables for which ACS 2005-09 BG level data are tabulated.
The scope of these tables differs markedly from the set of detailed tables/estimates available for areas other than block groups.
Use the interactive table to browse tables or search on your keywords to determine what block group level data
are available and view the subject matter items in tables of interest.
In December 2010 this table will be augmented to provide block group data access and analysis.
... an update to the table presented below will be posted week of 12/13/10.
ACS 2006-08 All Tabulation Areas Interactive Ranking Table

Select State using State drop-down to view data in one state.
Click column header to sort; click again to sort other direction.
See notes below about ranking table content & use. See related Ranking Tables Main Page
More about using the above ranking table and data ...
The ACS 2006-08 ranking table, shown above, contains a set of rows/records for all tabulation areas from the
ACS 2006-2008 3-year program. These are geographic areas with population 20,000 or more.
The rightmost columns of the ranking table are ACS 2006-08 estimates for the tabulation area:
Population - total population
%HS Grad+ - percent high school graduates & higher (table B15002, population 25 yrs & older)
%Bchlr Deg+ - percent bachelor degree & higher (table B15002, population 25 yrs & older)
Using the buttons below the ranking table, select a state of interest and then optionally a summary level (SumLevel) of interest.
The table refreshes with only these tabulation areas.
Next, click on a subject matter column header to rank areas in ascending or descending order.
Click that column header again to rank in other direction.
The ranking table data were developed with a special program that processes the
ACS0608 summary files.
The software processes the full 1.9GB "all_ACSSF.zip" in two steps.
In step one a master file is developed in dbase structure that contains the "geographic header record" for all tabulation areas
(see page 13 in technical documentation
for a list of items).
In a second step, the all U.S. master file is processed and specified subject matter fields are then integrated into the master file.
Also in the second step, a supplemental area name field (shortname) is created and added to the master file.
An extract file is generated that contains the selected fields shown in the ranking table (including the shortname in the AreaName column).
